The Bestek 300W Power Inverter is my recommended product in case you’re still wondering how to charge a laptop in a car.

With around 5,000 customer reviews on Amazon.com, you really can’t go wrong with a product that is popular among other consumers.

Bestek is a popular brand that deals in Power Inverters of various shapes, sizes and power ratings, one that even looks like a Coffee Mug.

Almost Bestek products have raving reviews on Amazon, hence be rest-assured that you’re in safe hands.

Moreover, with its capacity of 300W, you can charge your laptop at the same speed like it’s connected to an actual power outlet in your home or office.

It comes with two AC outlet; however, my recommendation would be only to use one at a time because you wouldn’t want to put more strain on your car battery, would you?

Additionally, it comes with dual USB ports that collectively offer power output of 4.2A, enough to power your smartphone and tablet simultaneously.

Note: The Bestek 300W Power Inverter has a switch to Turn On/Off AC Output; however it doesn’t shut off power to USB ports. Hence you’d be better off removing the Power Inverter from the socket when not in use; otherwise, it will slowly drain your car battery without your notice.

Will an Inverter Drain Car Battery?

A Car Power Inverter comes with different power ratings like 150W, 300W and all the way up to 2000W and 5000W.

However, for your use, any Car Inverter with rating of 150W and 300W is enough, anything more than that will drain your car battery faster.

Moreover, it is advisable not to use the Car Power Inverter when your car is stalled; otherwise, the battery drain will be quick too.

For your reference, a car battery is charged via an ‘Alternator’ that converts engine’s pistons mechanical energy into electrical energy and stores it into the car’s battery.

The car battery then powers other electric components like Ignition, Headlamps, Taillights, Wipers, In-Car Entertainment System, AC and as so on.

Are Power Inverters Bad for your Car?

No.

The 12V socket is designed to supply 12V at max.

However, what’s risky is how you use the Power Inverter and which Power Inverter it is.

Ideal power rating for a Power Inverter for a Hatchback and Sedan is between 150W and 300W, anything more than will result in faster battery drain.

However, make sure to buy Power Inverter from a reputed brand (like the one I recommended) otherwise a cheap inverter may draw more power from 12V port, which will result in a blown fuse.

Another thing to notice is, even though a Power Inverter provides an AC outlet, it is advisable to use it for low-power electronics like smartphone/camera/Bluetooth speaker charger, light stand, computer monitor, Gaming Laptops and so on.

However, if you got out on camping or a long trip, it is not advisable to use high-power consuming electronics like:

It comes with an extremely portable size of 3.2 inches that can easily fit anywhere in your car; however, it comes with a small cable length of 10 inches.
